CONTROL

Lets begin with an example, in most Indian homes cooking gas is delivered not via pipelines but through LPG cylinders, which basically contains butane gas with a little mercaptain added to it ( Mercaptain is added so that in case of a cylinder leakage, the user gets some odor and takes steps to prevent a fire). Now Butane is a highly inflammable gas. Suppose the entire cylinder leaks and matchstick or a lighter is struck then it can result is a devastating explosion and fire. The gas is the source of energy, when energy is uncontrolled and in huge amounts it can cause havoc.

Now if the same gas is in the cylinder and we put a regulator that controls the flow of the gas to the oven. When you light up the oven, you have a controlled amount of fire on which you can cook.

The above example shows us the importance of control and regulation. It is important in every sphere of life.
Control is vital and important in every activity. Without proper controls no system can be built. The human body has control systems in form of hormones that control the rate at which we are going to grow and the extent to which we are going to grow. When the cell division of our body goes beyond control is results in cancer.

The heart pumps blood to every organ of our body. The amount of blood that is pumped is in a regulated amount. If this control is not there and the heart beats in a haphazard fashion, the blood flow to different organs may go too high or too low at times which may damage the organ.

The electronics that you use Televisions ,Refrigerators , air-conditioners , fans etc all have control systems that controls the amount of power that is drawn from the power source. If there is too much power the device maybe damaged, if there is very little power the device will not work. Again appliances like refrigerator , aircontioners have control systems that controls the temperature of each part of the appliance. Without it the appliance will not achieve the target for which it was made.

The above examples gives us an idea that every system, whether it is man made or natural has to have good control systems otherwise the existence of a system is not possible.

In the yogic practice of Pranayama the yogi first tries to control the vital force of life(Prana) by controlling his breath. The breath is like the fly wheel of body, it is not exactly the breath but the lung motion that is first of all controlled, as a result the nerve impulses that control the lung motion are brought under control, from this the brain and various nerve currents running across the body are brought under control after that , thoughts are brought under control and then, the cause of energy the vital force or Prana' is brought under control.

We see the concept of control everywhere but it is so common that we tend to give very little importance to it. There is so much to learn if we again start questioning,observing and analysing every little event happening around us like a child.
